Install and run on GitLab CI/CD, Kubernetes, Linux and Buildah | CI/CD | Getting Started

Prepare the infrastructure

Requirements

GitLab;
Kubernetes to run GitLab Kubernetes Executor.

Install GitLab Runner

Follow official instructions to install and register the GitLab Runner. If you are going to install your GitLab Runner in Kubernetes, then install it to gitlab-ci namespace.

Setting up the build environment with Buildah

(For Ubuntu 23.10 and later) on the GitLab Runner host run:

{ echo "kernel.apparmor_restrict_unprivileged_userns = 0" && echo "kernel.apparmor_restrict_unprivileged_unconfined = 0";} | sudo tee -a /etc/sysctl.d/20-apparmor-donotrestrict.conf && sudo sysctl -p /etc/sysctl.d/20-apparmor-donotrestrict.conf

Basic GitLab Runner configuration (no caching)

Add the following to the GitLab Runner configuration file config.toml:

[[runners]]
  environment = ["FF_USE_ADVANCED_POD_SPEC_CONFIGURATION=true"]

  [runners.kubernetes]
    namespace = "gitlab-ci"

    [runners.kubernetes.pod_annotations]
      "container.apparmor.security.beta.kubernetes.io/build" = "unconfined"

    [runners.kubernetes.pod_security_context]
      run_as_non_root = true
      run_as_user = 1000
      run_as_group = 1000
      fs_group = 1000

    [[runners.kubernetes.volumes.empty_dir]]
      name = "gitlab-ci-kubernetes-executor-werf-cache"
      mount_path = "/home/build/.werf"

    [[runners.kubernetes.volumes.empty_dir]]
      name = "gitlab-ci-kubernetes-executor-builds-cache"
      mount_path = "/builds"

    [[runners.kubernetes.volumes.empty_dir]]
      name = "gitlab-ci-kubernetes-executor-helper-home"
      mount_path = "/home/helper"

    [[runners.kubernetes.pod_spec]]
      name = "fix helper HOME"
      patch = '''
        containers:
        - name: helper
          env:
          - name: HOME
            value: /home/helper
      '''
      patch_type = "strategic"

Basic GitLab Runner Configuration (with caching using Persistent Volumes)

Add the following to the GitLab Runner configuration file config.toml:

[[runners]]
  environment = ["FF_USE_ADVANCED_POD_SPEC_CONFIGURATION=true"]

  [runners.kubernetes]
    namespace = "gitlab-ci"

    [runners.kubernetes.pod_annotations]
      "container.apparmor.security.beta.kubernetes.io/build" = "unconfined"

    [runners.kubernetes.pod_security_context]
      run_as_non_root = true
      run_as_user = 1000
      run_as_group = 1000
      fs_group = 1000

    [[runners.kubernetes.volumes.pvc]]
      name = "gitlab-ci-kubernetes-executor-werf-cache"
      mount_path = "/home/build/.werf"

    [[runners.kubernetes.volumes.pvc]]
      name = "gitlab-ci-kubernetes-executor-builds-cache"
      mount_path = "/builds"

    [[runners.kubernetes.volumes.pvc]]
      name = "gitlab-ci-kubernetes-executor-helper-home"
      mount_path = "/home/helper"

    [[runners.kubernetes.pod_spec]]
      name = "fix helper HOME"
      patch = '''
        containers:
        - name: helper
          env:
          - name: HOME
            value: /home/helper
      '''
      patch_type = "strategic"

    [[runners.kubernetes.pod_spec]]
      name = "fix volumes permissions"
      patch = '''
        initContainers:
        - name: fix-volumes-permissions
          image: alpine
          command:
          - sh
          - -ec
          - |
            chown :$(id -g) /home/build/.werf /builds /home/helper
            chmod g+rwx /home/build/.werf /builds /home/helper
          securityContext:
            runAsUser: 0
            runAsNonRoot: false
          volumeMounts:
          - mountPath: /home/build/.werf
            name: gitlab-ci-kubernetes-executor-werf-cache
          - mountPath: /builds
            name: gitlab-ci-kubernetes-executor-builds-cache
          - mountPath: /home/helper
            name: gitlab-ci-kubernetes-executor-helper-home
      '''
      patch_type = "strategic"

Create PVCs:

kubectl create -f - <<EOF
---

EOF

Configure access to Kubernetes from GitLab Executor Pods

werf will run in GitLab Kubernetes Executor Pods. Usually you are going to deploy with werf to the same cluster where GitLab Kubernetes Executor Pods are running. If so, you need to configure custom ServiceAccount and ClusterRoleBinding.

Create a ServiceAccount and a ClusterRoleBinding:

kubectl create -f - <<EOF
---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: gitlab-ci-kubernetes-executor
  namespace: gitlab-ci
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: gitlab-ci-kubernetes-executor
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: gitlab-ci-kubernetes-executor
    namespace: gitlab-ci
EOF

For greater security, consider creating a more restricted ClusterRole/Role and using it instead of the cluster-admin cluster role above.

Now add this line to the GitLab Runner configuration file config.toml:

[[runners]]
  [runners.kubernetes]
    service_account = "gitlab-ci-kubernetes-executor"

Allow FUSE (for Kubernetes Nodes with Linux kernel older than 5.13)

If the Kubernetes Nodes on which you are going to run Kubernetes Executor Pods have Linux kernel version older than 5.13, then you need to allow FUSE:

kubectl create -f - <<EOF
---
apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: fuse-device-plugin
  namespace: kube-system
spec:
  selector:
    matchLabels:

  template:
    metadata:
      labels:
        name: fuse-device-plugin
    spec:
      hostNetwork: true
      containers:
      - image: soolaugust/fuse-device-plugin:v1.0
        name: fuse-device-plugin-ctr
        securityContext:
          allowPrivilegeEscalation: false
          capabilities:
            drop: ["ALL"]
        volumeMounts:
          - name: device-plugin
            mountPath: /var/lib/kubelet/device-plugins
      volumes:
        - name: device-plugin
          hostPath:
            path: /var/lib/kubelet/device-plugins
---
apiVersion: v1
kind: LimitRange
metadata:
  name: enable-fuse
  namespace: gitlab-ci
spec:
  limits:
  - type: "Container"
    default:
      github.com/fuse: 1
EOF

Preparing Kubernetes for multi-platform building (optional)

This step only needed to build images for platforms other than host platform running werf.

kubectl create -f - <<EOF
---
apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: qemu-user-static
  namespace: gitlab-ci

Configuring the container registry

Enable garbage collection for your container registry.

Configure the project

Configuring the GitLab project

Enable Require a successful pipeline for merge requests.
Enable the option to auto-cancel redundant pipelines.
Create and save the access token to clean up the no longer needed images from the container registry with the following parameters:
- Token name: werf-images-cleanup;
- Role: developer;
- Scopes: api.
Add the following variables to the project variables:
- werf version:
  - Key: WERF_VERSION;
  - Value: 2 stable;
- Access token to clean up the no longer needed images:
  - Key: WERF_IMAGES_CLEANUP_PASSWORD;
  - Value: <"werf-images-cleanup" access token you saved earlier>;
  - Protect variable: yes;
  - Mask variable: yes.
Add a scheduled nightly task to clean up the no longer needed images in the container registry by setting the main/master branch as the Target branch.
